Frequently asked questions
What is page interleaving?
Interleaving alternates pages from two PDFs: page 1 from file A, page 1 from file B, page 2 from A, page 2 from B, and so on.
When is interleaving useful?
Most commonly used for double-sided scanning — scan front sides as one PDF and back sides as another, then interleave to reconstruct the original order.
What if the two PDFs have different page counts?
The tool handles unequal page counts — remaining pages from the longer document are appended at the end.
Can I interleave more than two PDFs?
Currently, interleaving supports two PDFs at a time. For more files, run the operation multiple times.
